Melanin pigmentation patterns are ubiquitous in animals and function in crypsis, physical protection, thermoregulation and signalling. In vertebrates, pigmentation patterns formed over large body regions as well as within appendages (hair/feathers) may be due to the differential distribution of pigment producing cells (melanocytes) and/or regulation of the melanin synthesis pathway. We took adv...

We provide a new channel through which monetary policy has distributional consequences at business cycle frequencies. show that an unexpected easing increases labor income inequality between high-skilled and less-skilled workers. To rationalize these findings, we build New Keynesian DSGE model with asymmetric search-and-matching (SAM) frictions capital-skill complementarity (CSC) in production....

Efficient gene transfer to muscle stem cells (satellite cells) has not been achieved despite broad transduction of skeletal muscle by systemically administered adeno-associated virus serotype 2/9 (AAV-9) in mice. We hypothesized that cellular migration during fetal development would make satellite cells accessible for gene transfer following in utero intravascular injection. We injected AAV-9 e...

Vasoactive intestinal peptide (VIP) is an important growth regulator of the embryonic day (E)9-E11 mouse. In comparably aged rat embryos, VIP messenger RNA (mRNA) is not detectable; however, peak concentrations of VIP in maternal rat serum indicate a nonembryonic source. In the current study, mouse maternal and embryonic tissues were examined from E6-E12. Although RT-PCR revealed VIP mRNA in E6...

We included in our study nine normal human thymuses and sixteen thymomas (1 type A, 2 type AB, 3 type B1, 3 type B2, 5 type B3 and 2 type C). The 25 patients were between 7 days and 75 years old, and were submitted to open surgery for correction of congenital heart defects or for mediastinal tumor mass. Biopsies were formalin fixed for 24 hours and then embedded in paraffin using routine proced...

Most female birds develop only a left ovary, whereas males develop bilateral testes. The mechanism underlying this process is still not completely understood. Here, we provide a comprehensive transcriptional analysis of female chicken gonads and identify novel candidate side-biased genes. RNA-Seq analysis was carried out on total RNA harvested from the left and right gonads on embryonic day 6 (...

The prevalence of maternal smoking remains surprisingly high, ranging from 10-50% of pregnant women across different countries and socioeconomic groups. This is associated with several adverse neurological outcomes including increased risk for Sudden Infant Dealth Syndrome, attention deficit disorder, and autism. Prenatal exposure to carbon monoxide (CO), a major toxic constituent of cigarette ...

Features in Photoluminescence Map of SWNTs Over the past seven years photoluminescence (PL) spectroscopy has emerged as an important characterization tool for determining the (n, m) chirality and population of semiconducting SWNTs. This technique is essential for the chirality selective growth and/or the separation depending on chirality. Under excitation with the appropriate wavelength of ligh...

Experimental observations of spherical CdSe nanocrystals have shown that as the average radius, R, increases from 0.6 nm to 4.15 nm, the photoluminescence emission color changes from blue to red, and the photon energy of the first absorbance peak, E12, decreases from 3.02 eV to 1.88 eV 24 and eventually approaches the bandgap energy, Eg = 1.7 eV, of bulk CdSe. Various theoretical approaches hav...

We develop a theory of low-frequency movements in inflation expectations, and use it to interpret joint dynamics expectations for the United States other countries over postwar period. In our theory, long-run are endogenous. They driven by short-run surprises, way that depends on recent forecasting performance monetary policy. This distinguishes from common explanations properties inflation. Th...
